UNITED STATES FREDnnIcKvA. scIIossow, F DETROIT, MICHIGAN TOILET BOWL Application led July 2, 1930.

10 has been made-so called quiet bowls now` on the market are far from Ibeing noiseless.

The primary object of the present invention is to provide a bowl in which the air normally entrained in the iiushing rim is not expelled with the water into the bowl,

thus eliminating the noise that wouldotherwise follow.

A further object of the invention istov provide a construction which will insure a quick, positive siphonage of the bowl without any possibility ofthe water backing up into the bowl after siphonage has once been,

established.

With the foregoing and other objects in View which will appear as the description proceeds, the invention further resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes may be made in the precise embodiment of the invention herein disclosed with-l out departing from the spirit of the same.

In the drawings accompanying this speciiication: i Figure l is a vertical longitudinal sectional view through the bowl, with parts broken away to more clearly disclose the construction.

Figure 2 is a plan and horizontal sectional view taken on or about line'Q-Zof Figure l.

bigure 3 is a side elevation with parts broken away and in section showing the jetduct leading from the water inlet to the Vjet well, also in dotted lines avalve controlling the delivery of water to the bowl from a water main.

of construction, partly in section, taken on or about line 5-5'of Figures l and 2.

Referring now to the letters ofV reference placed upon the drawings:

, A denotes the closet bowl in its entirety.

B indicates a valve controlling the delivery of water from a source of supply into a chamber C from which it passes through a duct D into the flushing rim D1 and thence through a plurality of discharge ports D2 below the rim. with openings directed toward the wall of the bowl to provide a suitable wash-down. One of these discharge ports (D3) is relatively larger than the others, the purpose of which will be hereafter explained. i

Extending downwardly from the chamber C on oppositesides of the bowl and formed in the outer walls of the latter are a pair of jet ducts E, E-see Figures 2 and 3, also .in dotted lines in Figure ll,-into a pair of transversely extending channels El, E1 openving into a jet wall FP.

F denotes the up-leg of the siphon, G the vdowndeg of the siphon and H the outlet of the siphon, the respective ducts F, G and H forming togetherwhat is known in the art as a siphon trap.

I is an auxiliary water chamber connected with the flushing rim D1 by a duct Ia.

J denotes a conduit extending through the jet well Ea, for connecting the auxiliary water chamber l with the lower, or submerged portion of the bowl, it being noted that the water in the lower part of the jet well Ea is free to pass around the conduit J into the upper portion of the jet well, see Figures 1 and 4.

- K indicates 'a port or jet opening from the upper end of the jet well Ea into the bowl and L a port leading from the lower end of the jet well into the bowl and in axial alignment with the up-leg F of the siphon-trap.`

L? denotes the normal water level in the bowl and Ma the water line in bowl when siphonage occurs.

The flushing rim is divided at the front of the bowl by two partitions Da, Da spaced apart-se-e Figures 2 and 5, with a port Db, Db extending through the upper portion 'of each wall thereby forming a pocket Dc below Vthe ports D", which may or may not be provided with an outlet Dd discharging against the inner wall of the bowl,- see Figures 1 and 5.

It will bev noted that the duct I, leading to the auxiliary water chamber I opens into the pocket formed between th-e partitions Da, D,- see Figures 2 and 5.

The horizontal discharge ports D2 extending through the crenelated lower wall of the flushing rim are directed at a tangent to the curved surface of the bowl and serve to effect a whirling motion of the water and thereby hasten a thorough scrubbing of the surface of the bowl as it is discharged.

Having indicated the several parts by reference letters, the construction and operation or" the device will be readily understood.

lVater is admitted to the chamber' C by the manual operation of the valve B, a portion of which passes through the port D into the `flushing rim D1. rEhe remainder of the water passes through the jet dncts E, .E into the opposing transversely extending channels emptying into the jet well E .and thence into the bowl through the ports l and L.

A portion of the water entering the lushing rim passes to the bowl through the ports D2 and D" while the remainder flows through ports Db D into the pocket Dc thence through duct l into the auxiliary water chamber I, thence through conduit J into the bowl. A. portion of the water in the pocket Dc may alf-c pass through the outlet Dd against the inner wall of the howl.

All the air contained within the iushing rim or that entering the rim from the chamber C is carried through ports D Db into the water chamber l, where it remains until the flush is terminated, when the chamber refills with water to the normal water level La.

This eliminates the noise present when the air is expelled through the flushing rim ports into the 1cowl.

The rim ports D2 and D3 are designed to direct the water against the inner surface of the bowl at an angle which will cause the water to spread evenly over the entire area o the bowl and also impart a whirling motion to the water therein. Discharge port D3 admits a larger volume of water than thc ports D 2 and thereby forces up a wave of water at the front of the bowl which flows downwardly in such manner as to assist in washing foreign matter to ard the entrance to the up-leg F, of the Siphon-trap.

Jets ot water, at predetermined and varying angles are directed into the up-leg F ot the Siphon-trap though ports J, K and L to accelerate the flow of water through the trap, thereby hastening the moment of siphonic action in the trap.

rlthe described combined whirling and jet enforced movement quickly induces a Siphonic action sufficient to lower the central portion of the water within the bowl to the line Ma or slightly below the latter, thereby draw'- in foreign matter into the trap.

i(lie port or `iet K, which may be multiple, prevents eddies from forming at or near the entrance to the trap, and assists in washing foreign matter into the latter.

The conduit J is directed toward the top wall of the up-leg F of the Siphon trap and prevents eddies or pockets forming at the entrance ot the up-leg,-a common occurrenee in bowls wherein a considerable volume of air enters the trap at that point.

Having thus described my invention, what I claim is l. In a toilet bowl avalvecontrolled chamber adapted for connection with a source ot water supply; a rim channel encircling the bowl and connected with the chamber having a plurality of outlets for the discharge ot water against the inner face of the bowl, said channel being adapted to deliver air entrained with the water into a body of water previously delivered to the bowl, whereby noises'due to the escape of air are eliminated; tortuous passages forming a siphon trap with an inlet from the bowl and a discharge outlet for connection with a soil pipe; a water chamber located below the rim channel connected therewith by a duct for the passage ot air and water into said water chamber; ducts leading downwardly from the valve controlled inlet water chamber to a jet well having a lower port opening directed into the bowl at the opening into the siphon trap; and

a conduit extending through the jet well con- 1 necting the water chamber below the rim channel with the bowl, adjacent the lower port opening of the jetwell, said jet well having also a port opening into the bowl above the conduit opening into the latter.
